DOCKSCORE

DOCKSCORE ranks protein-protein docked poses by scoring interface properties to identify native or near-native interactions.

Key Features:

• Objective Scoring Scheme: Evaluates docked poses using multiple interface parameters to produce comparative scores.
• Surface Area: Assesses the extent of contact between interacting protein surfaces at the interface.
• Evolutionary Conservation: Considers conserved residues at the interface that are often crucial for binding.
• Hydrophobicity: Evaluates hydrophobic interactions contributing to complex stability.
• Short Contacts: Analyzes short interatomic distances indicative of strong interactions.
• Spatial Clustering: Examines the distribution and clustering of interface residues that can influence binding affinity.
• Scoring and Ranking Capabilities: Integrates parameter scores to generate a ranked list of docked poses.
• Data Output Options: Produces scores and ranks for evaluated poses and provides CSV output and graphical representations of interfaces.

Scientific Applications:

• Identification of native/near-native conformations: Ranks docking solutions to prioritize poses most consistent with native protein-protein interactions.
• Interface analysis: Enables assessment of residue-level determinants such as conservation, hydrophobicity, and contact patterns at interfaces.
• Prioritization for experimental validation: Helps select high-scoring docked poses for downstream experimental testing.
• Assessment of interaction modes: Supports comparative evaluation of alternative binding modes generated by docking simulations.

Methodology:

Computational scoring of docked poses using interface parameters—surface area, evolutionary conservation, hydrophobicity, short contacts, and spatial clustering—followed by integration of parameter scores to rank poses and output scores and ranks as CSV and graphical interface representations.
